Question

Between the time Iko woke up and lunchtime, the temperature rose by 11. Then by the time he went to bed, the temperature dropped by 14.

What is the value of the remaining integer chips after the zero pairs are removed?

Answer 1

The value of the remaining integer chips after the zero pairs are removed is -3

Explanation:

Given:

Temperature rise between woke up and lunchtime = 11

Temperature dropped when Iko went to bed = 14

Questions:

1. Write an addition expression for the temperature relative to when Iko woke up.

⇒ 11 + (-14)

2. What is the value of the remaining integer chips after the zero pairs are removed?

⇒
`11+(-14)`

⇒
`11-14`

⇒
`-3`

3. What is the net change in the temperature relative to when Iko woke up?

⇒ Net change =
`-3`°

⇒ Loss of
`3` degree.

The value of the remaining integer chips after the zero pairs are removed is -3
